Why do girls (women) draw weird tats on their bodies like that for?

SO I WENT TO THIS RESORT AND I SAW THIS GORGEOUS GIRL LAYING DOWN ON HER BEACH CHAIR JUST WHEN I WAS ABOUT TO GO UP AND TALK TO HER I NOTICED SHE HAS A VERY UNUSUAL TATTOO ON HER RIGHT THIGH TO ME IT LOOKS LIKE A SWASTIKA; AT THIS POINT I'M TOO AFRAID TO ASK HER IF SHE IS A NAZI AND I'M ALSO TOO AFRAID TO TELL HER TAHT I'M JEWISH
